NEET BIOLOGY

Detailed explanation-1: -By eating plants. You can obtain amino acids. So the answer for this problem will be auction be eating plants.

Detailed explanation-2: -Decomposition. Plants take up nitrogen compounds through their roots. Animals obtain these compounds when they eat the plants.

Detailed explanation-3: -Animals get these amino acids by eating plants or animals that eat plants. This works because plants can make all twenty amino acids including the ten or so “essential” ones that most animals can’t.

Detailed explanation-4: -Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

Detailed explanation-5: -Plants get the nitrogen that they need from the soil, where it has already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3), thereby breaking the tough triple bond of molecular nitrogen.
